Problems solved by technology

In the production process of PET film, the storage hopper is connected with the conveying pipe, and the conveying bolt located inside the conveying pipe is connected by the rotation of the motor to realize the material conveying. It is easy to block between the material pipes; the second is that the storage hopper is relatively high, and it is necessary to climb to the top of the storage hopper through a ladder to observe the remaining solids in the storage hopper, which is inconvenient to operate

Abstract

The invention provides a PET film, and relates to the technical field of PET film preparation. The PET film is prepared from the following components: 75-85 parts of PET particles, 1-2 parts of nano titanium dioxide, 4-7 parts of polyvinyl alcohol and 1-2 parts of nano boron nitride. The preparation process comprises the following steps: step 1, putting PET particles, nano titanium dioxide, polyvinyl alcohol and nano boron nitride into a fuse machine for heating, stirring and melting to obtain a miscible material; and 2, crystallizing and removing impurities from the mixed and dissolved material obtained in the step 1, drying the obtained crystal in drying equipment, and granulating the dried crystal material in a granulator to obtain PET mixture solid particles.

Description

technical field [0001] The invention belongs to the technical field of PET film preparation, in particular to a PET film. Background technique [0002] PET film has good light transmission performance, air tightness performance and mechanical performance. PET film can not only be used in product packaging to achieve effective moisture resistance and fragrance retention, but also can be used together with other thin-layer materials to prepare composite substrates, which can be used as substrate materials in circuits. [0003] Production of PET film Through casting film equipment, PET solid particles are melted into liquid state and rolled into film form. In the production process of PET film, the storage hopper is connected with the conveying pipe, and the conveying bolt located inside the conveying pipe is connected by the rotation of the motor to realize the material conveying. Blockage is prone to occur between the feed pipes; the second is that the storage hopper is rel...
